GAS LIFT OPERATION
INTRODUCTIONDefinition :
Gas Lift is an artificial lift method that uses energy from the gas (high gas pressure), which is inserted in annulus and the gas will enter to tubing string through gas lift valve to provide lifting energy.
The purpose are :Increasing well productionReviving dead well
GAS LIFT OPERATION
INTRODUCTION
Type of gas lift :Based on the equipment used : - Annulus
(SPM) - Macaroni
Based on the flow of gas : - Continuous - Intermittent

CONCLUSIONGas lift are installed for increasing well
production and reviving dead well by inject gas (high gas pressure) to the well , so fluid can flow to the surface.
